What Are the Standards and Regulation of Ringlock Scaffolding in the Projects
Construction ringlock scaffolding set-up brings to the construction personnel of the safety of everyone is visible, the scaffolding for all construction personnel to greater security, so be sure to check and accept, so how about scaffolding acceptance standard specifications? With the manufacturer to look at the following introduction:
1, scaffolding, construction director shall, in accordance with requirements of the construction schemes, in combination with the construction site operation conditions and team, do detailed disclosure, and specialist command.
2, the height of the erection of the shape to conform to the requirements; shelves to strong stability, deformation; Set-up should be horizontal flat vertical pole, lap is strong; High homework scaffolding shall be installed lightning protection facilities; Steel stud, main rail joint should be staggered, lap length > 50 cm; Steel pipe scaffold made rod should be vertical stability on metal base or mat wood, in case of digging, should be tied to sweep the floor.
3, scaffolding are strictly prohibited to work overtime and scaffolding lateral setting the mesh type safety net, construction layer according to the rules set 2 m of the rail or net and pedal, construction layer under each from 10 m with closed flat screen or other measures, construction scaffolding poling and rock slope or between buildings nearly closed, according to the requirement to have the construction personnel shall be built up and down escalator,..
4, node connected to reliable. One of the fastener tighten degree should be controlled in torsion from 40 ~ 60 nm; Ringlock should cover the firm (the bowl on the tight);Steel wire cross tie points should be 1.5 ~ 2 times and banding, can not have obvious sprain, and steel wire in exposed length shall be 80 mm or more.
5, the level of the longitudinal steel flat bar deviation should be 1/250 or less, and the whole frame of long horizontal deviation should be < 50 mm. Wood, bamboo scaffolding lap flat bar according to the total length of epithelial trend line (that is, each pole epithelial line compromise position) examination, twice its level of deviation should be controlled in the range of allowable steel flat bar.
6, the verticality deviation of steel ringlock scaffolding stud should be 1/300 or less, and should be controlled at the same time the large vertical deviation value: when wearing high 20 m or less < 50 mm; When high rack > 20 m < 75 mm.
7, Ringlock scaffolding should be covered, can not have space, out of the board, the lap length > 20 cm, adversary lap, should set up double row putlog, distance is not more than 20 cm, scaffolding should be smoothly laid tie or nail up, homework layer planking, protective measures should comply with the requirements.
After 8, scaffolding, by construction, organization, head of the relevant personnel to participate in, according to the construction plan and specification section examination and acceptance of terms, determined to meet the requirements, the can be put into use.
